Step 1: Change the IE Concurrent Download Limit - Internet Explorer's default settings only enable you to download up to two downloads at the same time. Optimizing the download settings enables you to download up to 16 files concurrently from the same server.
Method - Open registry editor and navigate to the following key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings
Right click the right pane and select New->DWORD Value. Type MaxConnectionsPer1_0Server and give it a value of 16. Add another DWORD using the same process - call it MaxConnectionsPerServer with the same value - 16.
Step 2: Disable Windows Indexing Service - The indexing feature consumes system resources, and may adversely affect your system's performance. By disabling the indexing feature, you free up disk space on your computer and may improve its performance.
Method - Start Internet Explorer, Select Tools -> Internet Options ->General. Under Temporary Internet Files click the Settings button and type the amount of disk space to use.
Method - Goto Start -> Control Panel -> System. Click the Advanced tab, and under Performance, click the Settings button. Clear the Fade or slide menus into view check box, and then click OK. These excellent suggestions are based on a local optimization report generated by a tuneup utility that's available for Dell machines.
